Problems solved by technology

If the fixation of the fixture is not stable, resulting in displacement, dimensional deviation is likely to occur during processing, and the accuracy cannot be guaranteed, resulting in quality problems. Moreover, the existing fixture generally only has a fixed function and cannot rotate and lift the casting at will. Inconvenience

Abstract

The invention discloses a clamp for casting machining, The clamp comprises a supporting table, a downwards-sunken positioning groove is formed in the upper surface of the supporting table, a positioning plate is arranged in the positioning groove, a bottom plate is arranged below the supporting table, a fixing disc is arranged above the bottom plate, a first rotating shaft is arranged above the fixing disc, a supporting disc is arranged above the first rotating shaft, an electric push rod is arranged above the supporting disc, the upper end of the electric push rod is connected with the bottom of the positioning plate, a plurality of clamping mechanisms are arranged on the positioning plate, and auxiliary fixing mechanisms are arranged on the two sides of the positioning groove. According to the clamp , the positioning plate capable of rotating and lifting is arranged in the positioning groove, so that a casting can be conveniently and directly subjected to rotating fit machining after being fixed by the clamp, and the casting machining efficiency is improved; and through a clamping mechanism and the auxiliary fixing mechanisms, fixing of the clamp to the casting is effectively reinforced, the casting is prevented from displacement, and the casting machining precision is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of casting processing, especially the technical field of fixtures for casting processing. 【Background technique】 [0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into the pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is polished and other subsequent processing methods , the resulting object has a certain shape, size and performance. Castings have a long history of application. In ancient times, people used castings to make and some living utensils. In modern times, castings are mainly used as blanks for machine parts, and some precision castings can also be directly used as machine parts. Castings account for a large proportion of mechanical products. For example, in tractors, castings account for about 50-70% of the weight of the whole machine, 40-70% in agricultural machinery, ...
